Analog Devices Inc. MAX20010x Step-Down Converters
Analog Devices Inc. MAX20010x Step-Down Converters operate with a 3.0V to 5.5V input voltage range and provide a 0.5V to 1.5875V output voltage range. The wide input/output voltage range and the ability to provide up to 6A load current make these ICs ideal for onboard point-of-load and post-regulation applications. The MAX20010C, MAX20010D, and MAX20010E achieve ±2% output error over load, line, and temperature ranges. The MAX20010D/MAX20010E offers improved transient responses.
The ICs feature a 2.2MHz fixed-frequency PWM mode for better noise immunity and load-transient response, and a pulse-frequency modulation mode (skip) for increased efficiency during light-load operation. The 2.2MHz frequency operation allows the use of all-ceramic capacitors and minimizes the solution footprint. The programmable spread-spectrum frequency modulation minimizes radiated electromagnetic emissions. Integrated low RDS(ON) switches improve efficiency at heavy loads and make the layout a much simpler task with respect to discrete solutions.
The ICs are offered with factory-preset output voltages. An I2C interface supports dynamic voltage adjustment with programmable slew rates. Other features include programmable soft-start, overcurrent, and overtemperature protection.
